COMMERCIAL  FERTILIZERS 

By  P.  L.  HIBBARD 


This  bulletin  comprises  the  results  of  the  fertilizer  inspection  work 
of  the  California  Fertilizer  Control  for  the  fiscal  year  ending  June  30, 
1918. 

PURPOSE  AND  FUNCTIONS  OF  THE  FERTILIZER  CONTROL 

The  duty  of  the  Fertilizer  Control  is:    * 

First:  To  issue  certificates  of  registration  to  manufacturers  and 
dealers  who  have  complied  with  the  law  by  filing  a  sworn  statement  of 
composition  and  sources  of  the  fertilizers  they  wish  to  sell. 

Second:  To  analyze  these  fertilizers  as  found  in  the  open  market 
and  publish  the  results  for  the  information  of  the  public.  If  a  manu- 
facturer sells  fertilizers  which  are  materially  below  his  guarantee  in 
composition  or  value  he  is  subject  to  prosectuion  and  fine.  By  this 
means  it  is  intended  to  insure  to  purchasers  that  the  fertilizers  they  buy 
shall  be  substantially  as  good  as  represented. 

By  a  study  of  the  reports  of  analyses  of  fertilizers,  the  consumer 
should  be  able  to  determine  whether  the  materials  he  buys  are  sold  for 
a  fair  price,  and  whether  he  obtains  fertilizers  of  the  desired  composi- 
tion. In  short,  the  function  of  the  Fertilizer  Control  is  to  see  that  the 
manufacturer  gives  the  consumer  a  square  deal. 

MAINTENANCE  OF  GUARANTEES 

Every  manufacturer  is  required  by  law  to  guarantee  the  percentage 
of  nitrogen,  phosphoric  acid  and  potash  in  the  fertilizers  he  sells.  Owing 
to  difficulties  of  sampling  and  analysis  the  law  permits  a  maximum 
deficiency  of  0.25%  nitrogen,  1.00%  phosphoric  acid,  0.50%  potash 
from  the  figures  guaranteed.  Greater  deficiences  than  these  are  regarded 
as  infractions  of  the  law,  and  are  indicated  in  the  report  of  analyses  in 
black  faced  type. 

Some  manufacturers  uphold  their  guarantees  better  than  others. 
The  following  table  is  a  condensed  report  of  the  deficiences  found  in 
the  main  table  of  analyses.  It  summarizes  the  work  done  in  this  labora- 
tory on  each  manufacturer's  goods.  The  columns  headed  Deficiencies — 
per  cent  of  possible,  may  be  used  for  comparison  of  the  various  com- 
panies as  to  probability  of  meeting  their  guarantees.  The  other  columns 
are  necessary  to  show  how  these  figures  were  obtained.  In  cases  where 
very  few  analyses  are  reported  for  a  manufacturer,  the  figures  should  be 
taken  with  caution,  as  perhaps  not  properly  representative.     When

proved March  20,  1903. 


126  UNIVERSITY   OF   CALIFORNIA — EXPERIMENT   STATION 

several  samples  of  one  manufacturer's  goods  were  analysed  the  figures 
may  be  accepted  as  probably  a  fair  indication  of  the  reliability  of  his 
guarantee. 

In  general,  manufacturers  have  more  than  maintained  their  guaran- 
tees, so  that  an  average  of  all  the  analyses  would  show  a  substantial 
increase  over  the  amount  guaranteed.

Owing  to  the  possibility  of  misunderstanding,  the  figures  for  percentage 
deficiences  are  not  given  in  above  table  in  cases  where  less  than  four  samples 
were  analyzed. 

Fertilizers  sold  on  Station  analysis,  and  some  others,  are  not  given  a 
valuation  in  the  table  of  analyses,  hence  the  number  of  such  samples  is 
deducted  from  the  total  number  analyzed,  in  computing  deficiences  in 
valuation.

COMMERCIAL    FERTILIZERS  127 

SUMMARY  OF  DEFICIENCIES 

In  the  analyses  of  the  above  samples,  the  following  number  of  defi- 
ciencies greater  than  those  allowed  by  law  occured: 

Available  phosphoric  acid  (total  when  available  is  not  guaranteed) 28 

Total  nitrogen 37 

Potash 3 

In  Valuation 1.5 

These  deficiencies  were  found  in  61  samples. 

Of  the  total  number  of  valuations  reported  in  this  bulletin  73%  arc 
above  the  amount  guaranteed  while  27%  fall  below. 

MECHANICAL  CONDITION  OF  FERTILIZERS 

A  good  degree  of  fineness  is  one  of  the  essential  qualities  of  a  good 
fertilizer.  It  may  be  assumed  that  the  finer  the  material  the  higher  the 
availability,  hence  the  consumer  should  insist  on  having  finely  ground 
fertilizers.  Unfortunately,  some  manufacturers  are  at  times  careless  in 
regard  to  the  fineness  of  their  goods.  The  insistent  demand  of  the  con- 
sumer is  the  most  effective  means  of  correcting  such  carelessness. 

Besides  the  low  agricultural  availability  and  the  difficulty  in  apply- 
ing coarse  fertilizers,  it  is  almost  impossible  to  obtain  adequately  repre- 
sentative samples  of  such  goods  for  analysis.  This  is  a  prolific  source  of 
dissatisfaction  and  disagreement  between  buyers  and  sellers.  During 
handling  and  transportation  a  coarsely  ground  tankage  will  separate  so 
that  the  top  of  the  sack  contains  the  coarser  material,  high  in  nitrogen, 
while  the  bottom  contains  the  finer  parts  of  bone,  high  in  phosphoric 
acid.  A  mixture  of  coarse  bone  meal  with  sulfate  of  potash  will  separate 
into  coarse  bone  at  the  top  and  excess  of  potash  at  the  bottom. 

One  of  the  chief  reasons  for  the  existence  of  the  fertilizer  manu- 
facturer is  that  he  is  better  prepared  than  the  farmer  to  grind  and  mix 
the  goods  he  sells,  and  the  farmer  should  insist  that  he  do  it  well. 

CAUTION  IN  REGARD  TO  LABELING  FERTILIZER  PACKAGES 

The  law  expressly  states  that  every  package  of  fertilizer  shall  be 
accompanied  by  a  plainly  printed  label  giving  the  brand  name,  analysis, 
and  source  of  the  materials  in  the  package.  This  requirement  is  not 
satisfactorily  met  by  some  manufacturers  and  dealers.  Farmers  are 
hereby  cautioned  that  if  they  buy  improperly  or  inadequately  labeled 
fertilizers  or  goods  not  sold  by  properly  registered  dealers  or  their 
authorized  agents  they  lose  the  protection  afforded  by  the  Fertilizer 
Control.  Consumers  should  insist  that  fertilizer  tags  show  plainly  both 
the  percentage  and  the  derivation  of  each  ingredient.    A  verbal  state- 


128  UNIVERSITY   OF   CALIFORNIA — EXPERIMENT   STATION 

ment  given  by  selling  agent  should  not  be  accepted  as  adequate.  The 
honest  manufacturer  is  willing  to  guarantee  his  goods  properly,  and  the 
farmer  will  best  serve  his  own  interests  by  dealing  with  no  other. 


FERTILIZER  VALUATIONS 

The  calculations  of  the  commercial  values  of  the  fertilizers  here 
reported  are  made  on  the  so-called  unit  basis.  Such  calculations 
consist  simply  in  multiplying  the  number  of  per  cent  of  each  ingredient 
by  the  price  per  unit  and  adding  the  products.  The  sum  thus  obtained 
is  the  commercial  value  per  ton  at  the  prices  used.  If  it  is  desired  to  use 
such  calculations  for  determining  the  amount  which  should  be  paid  for 
goods,  or  the  rebate  to  which  the  buyer  is  entitled,  owing  to  the  goods 
delivered  being  below  the  guaranty,  it  can  only  be  satisfactorily  done  if 
a  definite  price  per  unit  has  been  agreed  upon  between  buyer  and  seller. 
But  for  the  mere  purpose  of  showing  the  relative  values  of  goods  to 
guaranties,  it  is  not  at  all  necessary  that  the  prices  adopted  should  be 
the  exact  market  prices.  Thus  it  is  that  the  Fertilizer  Control  in  at- 
tempting to  show  the  relation  between  values  found  and  values  claimed, 
uses  a  schedule  which  is  admittedly  only  an  approximately  average  of 
market  values.  Owing  to  market  fluctuations,  differences  in  cost  of 
delivery  at  different  points,  and  other  causes,  the  obtaining  of  true 
average  market  prices  is  an  impossibility.  But  if  the  reader  will  bear  in 
mind  the  true  purpose  of  the  valuations  reported,  these  will  have  served 
their  turn  and  he  will  not  be  led  to  assume  that  the  experiment  station 
is  dictating  the  prices  at  which  goods  shall  be  sold. 


NOTE  IN  REGARD  TO  SCHEDULE  OF  VALUES 

In  view  of  the  continued  extraordinary  increases  in  prices  of  fer- 
tilizers and  of  the  choatic  condition  of  the  market,  we  find  it  impossible 
again  to  prepare  a  schedule  of  prices  by  consultation  of  market  reports 
as  heretofore.  Inasmuch,  however,  as  such  a  schedule  is  necessary  for 
comparative  purposes,  the  following  table  of  values  has  been  prepared, 
based  chiefly  on  known  prices  of  recent  sales  in  this  state.  These  values 
are  not  to  be  taken  as  in  any  way  representing  actual  present  market 
prices,  though  they  may  sometimes  approximate  them.  In  the  table  of 
analyses  the  column  "Value  per  ton"  is  given  on  the  basis  of  station 
prices.

SCOPE  OF  INSPECTION 

During  the  year  302  samples  of  fertilizers  and  fertilizing  materials 
have  been  received  at  this  laboratory.  Of  this  number  13  were  sent  by 
farmers  under  the  two-dollar  fee  provision,  186  were  taken  by  inspector^ 
from  purchasers'  goods  upon  the  request  of  the  purchasers,  and  78  were 
taken  by  inspectors  from  goods  in  the  hands  of  agents  and  manufacturers. 
25  samples  of  a  miscellaneous  nature  are  omitted  from  the  tables. 

The  following  classification  may  be  made  of  samples  reported  in  this 
bulletin:

REGISTERED  MANUFACTURERS  AND  DEALERS 

The  following  manufacturers  and  dealers  in  commercial  fertilizers 
have  obtained  certificates  of  registration  under  the  provisions  of  the 
California  fertilizer  law,  for  the  fiscal  year  beginning  July  1,  1917.  A 
list  is  also  given  of  the  brands  of  fertilizers  and  fertilizer  materials 
offered  for  sale  by  them.  According  to  the  sworn  returns  of  dealers 
registered  for  the  fiscal  year  ending  June  30,  1917,  their  entire  sales  in 
the  state  amounted  to  43,904  tons.  Incomplete  returns  for  the  year 
ending  June  30,  1918,  indicate  approximately  30,000  tons. 

No  dealer  or  manufacturer,  except  those  who  have  certificates  of 


130 


UNIVERSITY   OF    CALIFORNIA — EXPERIMENT   STATION 


registration  from  the  University  of  California,  and  their  authorized 
agents,  can  legally  sell  fertilizers  in  this  state.  No  person  or  company 
has  any  right  to  use  any  registration  number  except  in  connection  with 
the  firm  name  to  which  the  registration  certificate  of  such  number  has 
been  issued ;  and  no  person  or  company  to  whom  a  registration  number 
has  been  assigned  has  any  right  to  give  any  other  person  or  company  per- 
mission to  use  said  registration  number;  any  number  so  used  is  a  fraud. 
No  agent  has  any  right  to  use  his  principals'  registration  number  in 
connection  with  his  own  name.

152  UNIVERSITY    OF    CALIFORNIA — EXPERIMENT   STATION 


REPORT  OF  ANALYSIS 

Available  phosphoric  acid  is  not  determined  in  bone,  meal,  tankage, 
and  Thomas  phosphate  powder,  unless  requested.  The  fineness  of  these 
materials  is  determined,  fine  and  medium  bone  being  separated  by  a 
sieve  of  50  meshes  to  the  inch;  tankage  by  a  25-mesh  sieve;  and  Thomas 
phosphate  powder  by  a  100-mesh  sieve. 

Nitrogen  in  ammonium  salts,  will,  in  some  cases,  be  found  reporte:! 
when  nitrogen  in  this  form  is  not  guaranteed.  In  some  of  such  cases 
this  form  of  nitrogen  is  produced  by  conversion  of  organic  nitrogen 
during  process  of  manufacture,  and  is  not  to  be  considered  a  deviation 
from  guaranty  of  materials  used.  Guanos  carry  more  or  less  nitro- 
gen in  nitrates  and  ammonium  salts,  and  when  any  appreciable  quan- 
tity of  guano  is  used  the  manufacturer  should  take  into  account  the 
fact  that  some  nitrogen  will  show  as  nitrates  and  ammonium  salts. 
The  failure  to  take  this  into  consideration  may  account  for  the  appear- 
ance of  these  forms  of  nitrogen  in  some  samples  in  which  only  organic 
nitrogen  was  guaranteed. 

The  percentage  of  chlorin  is  given  when  it  exceeds  0.50  per  cent. 
It  is  a  matter  of  only  technical  interest  whether  chlorin  present  is  from 
muriate  of  potash,  kainit,  or  from  common  salt  that  may  be  in  some  of 
the  materials  used.  If  a  manufacturer  uses  sulfate  of  potash  and  a 
tankage  with  it  containing  a  large  amount  of  chlorin,  from  a  practical 
standpoint  he  has  changed  the  quality  of  his  fertilizer  just  as  much  as 
if  he  had  used  muriate  of  potash  instead  of  sulfate  of  potash.  Chlorin 
from  all  other  sources  has  the  same  effect  as  if  from  muriate  of  potash. 
However,  if  muriate  of  potash  is  found  when  sulfate  is  guaranteed,  the 
fact  will  be  published. 

The  following  abbreviations  are  used  in  the  tables:  Bat  G,  =  bat 
guano,  Bl  =  blood,  Bn  =  bone,  Fs  =  fish,  G  =  guano,  H  =  hoof,  Min. 
Phos  =  mineral  phosphate,  Super  =  superphosphates,  T  =  tankage, 
CSM  =  cotton  seed  meal. 

Guarantees  are  entered  in  italics.  Deficiencies  greater  than  those 
allowed  by  law  are  entered  in  bold  faced  type.
